The company said VEST (Venous External SupporT) is a kink resistant cobalt-chromium external support applied on the outer surface of saphenous
vein grafts when used in Coronary Artery Bypass Grafting (CABG) surgery.
This is currently the largest trial with long-term outcome data comparing these two types of stents in saphenous
vein graft disease, and will reassure clinicians about the use of DES for this specific indication, noted principal investigator Raban Jeger, MD, from University Hospital, in Basel, Switzerland.
A superficial dissection was done in the superficial fascia of the lower limb to dissect the GSV from its beginning in front of medial malleolus at ankle to its termination into the femoral vein in the upper thigh region at the saphenous
stripping using big olive heads for the proximal portion from the groin down to the level of the knee and using small olive heads for the distal portion from the knee to the level of the ankle is the alternative method which results in minimal nerve injury and vessel disruption.
The relation of risk factors to the development of atherosclerosis in saphenous
vein bypass grafts and the progression of disease in the native circulation: a study 10 years after aortocoronary bypass surgery.
The multicenter study included 224 randomized legs belonging to symptomatic patients with a target great saphenous
vein diameter of at least 5 mm.
All of these nerves are branches of the sciatic nerve except for the saphenous
, which is a branch of the femoral nerve.
Treatment of Primary Venous Insufficiency by Endovenous Saphenous
Previous studies suggest that 25 percent of saphenous
vein grafts clog within 12 to 18 months.
It has been reported that less than 1% of adults presenting with lower extremity pain suffer from saphenous
neuropathy, (9,10) however injury to the saphenous
nerve is associated with a number of surgical interventions commonly utilized in today's medical community.
Up to 25% of saphenous
vein grafts occlude in the first postoperative year, and annual occlusion rates thereafter are l%-2% until year 5 and 4%-5% from years 5-10.
CT angiography showed a saphenous
vein graft aneurysm (Figure).
Consider endovenous chemical ablation for treatment of tortuous saphenous
tributary varicosities that cannot be treated with thermal ablation.
Of the five peripheral nerves supplying the foot, four travel in close proximity to vessels: the deep peroneal (lateral to anterior tibial artery), posterior tibial (posterior to posterior tibial artery), saphenous
vein) and the sural nerve (short saphenous
During the procedure, the surgeon removes a healthy artery or vein from elsewhere in the body, most often the saphenous
vein in the leg, and uses it to route blood around a blockage in a coronary artery.
